Feasibility Analysis of Brewers’ Spent Grain for Energy Use: Waste and Experimental Pellets

Waste production is increasing every day as a consequence of human activities; thus, its valorization becoming more important. For this purpose, the usage wastes biofuels one most important aspects sustainable strategies. This case main waste generated in brewing industries: brewers’ spent grain (BSG). In sector, microbreweries are not able to properly manage that they generate due lack space. Consequently, transformation BSG high-quality biofuel might be an interesting option for kind small industry. work, we carried out physical-energy characterization BSG, well pellets from waste. The initial showed slightly unfavorable results concerning N and ash, with values 3.76% 3.37% db, respectively. Nevertheless, physical was very good, acceptable bulk density (662.96 kg·m?3 wb) low heating value (LHV; 17.65 MJ·kg?1 wb), among others. situation favorable any intended uses (for energy use or animal feed, others).
